ASS IGNOR TO MALVIN LIGHTER IIlTC A CORPORATION OF NEW YORK MECHANICALMEMORANDUM AND METHOD OF MAKING THE SAME Application filed August 13,1928. Serial No. 299,274.

My invention relates to structural improve-- ments in mechanicalmemorandums of the kind just mentioned, for improving the efliciencythereof, by giving to the construction an arrangement of the variousparts certain points of mechanical advantage.

My invention further relates to an improved method for shaping certainof the parts and for fitting them into position, with a minimumexpenditure of time and labor.

Further purposes and objects of my invention are brought out in thedescriptive matter set forth below.

drawings forming a part of this specification, and in which likereference characters indicate like parts throughout the several figures.

Figure 1 is a fragmentary plan of one of the blanks used in making myimproved mechanical memorandum, and it is cut from sheet material,preferably card-board or the like. I

Figure 2 is a fragmentary plan of another blank used in the constructionof my device,

' and having the form of a serrated strip made of sheet material, suchas card-board.

Figure 3 is a fragmentary plan of still another blank having the form ofa serrated strip made of sheet material such as cardboard, and used inmy construction.

Figure 4 is a fragmentary plan showing the blank appearing in Figure 1,and a pair of strips of the kind shown in Figure 2, as assembled andfitted together during the manufacture of my device.

Figure 5 is a fragmentary plan indicating a further step in manufacture,the two strips just mentioned having been cut into small pieces, eachhaving the form of a slide.

Figure (5 is a plan view of the finished art cle, certain parts beingbroken away.

l igure '1' is a section on the line 77 of Figure 6, looking in thedirection indicated by thearrows.

A blank 7, made of sheet material such as card-board, paste board,celluloid, thin leather or leatheroid, tough paper or the like, is cutout and rorined as indicated more particulariy in Figure l. I

lhe blank '2 is provided with flanges 8 and 9, and with end naps l0 and11, these all being preferably integral as shown.

'ine blank is i'urther provided with score lines l2, l2, 13, 13, and isadapted to be folded or bent, upon these score lines.

The blank is further provided with two rows of circular openings 14; and15, coinciding in general direction with the score lines 12, 12, and isfurther provided with two rows of openings, 16, 17, carried by theflanges 8 and 9, and having the form of arcuate slots. The purpose orthe openings 14, 15, 16, and 17,

t 1 is explained below. Relerence is made to the accompanying Inconnection with the blank 71 use two smaller blanks having the form ofstrips 18 and 19, of the kind shown in Figures 2 and 8,respectively,'and made of sheet material, in this instance card-board.During the manufacture of my device these twostrips are each connectedwith and fitted upon the blank 7, as indicated in Figure 1, but in thefinished article the two strips no longer appear as strips, they havingbeen cut into pieces each having the form of a slide, as may beunderstood by contrasting Figure t with Figures 5 and 6. l p The strip18 is provided with tongues 20, 21 and 22 integral with it, the tongues20 being somewhat longer than the tongues 21, and the tongues 22 beingof substantially the same length as the tongues 21.

The strip 19 is provided with tongues 23 exactly like the tongues 22,and is further provided with tongues 24, having the same form as thetongues 21 and being of the same length thereor".

in practice the two strips 18 and 19 are each laid upon the blank 7, andfor the time being secured thereto as above described. For this purposethe tongues 20 and 21 are tucked through the openin s 16, having theform of slots, and the tongues 22 are tucked through the circularopenings 1 Similarly the tongues 23 are tucked through the circularopenings 15, and the tongues 2a are tuck-ct through the slots 17.

This leaves the blank 7 with the strips and 19 in the conditionindicated in Figur Next the two strips 18 and 19 are each cut crosswise,so as to form from it a numberot separate pieces 25 and 26, each havingthe form of a slide, the slides being arrange 1 in two rowsparallel witheach otner, as indicated in Figure 5.

The step of cutting the strips crosswise i preferably effected by scansof cutting machinery adapted for the purpose, but may be done by hand.The main requirement in this all be severe respect is that each strip sa sufiicient number of places to co into slides, care being exercised tomake cuts in the right places in or ler to ren ler slides of properform.

The next step in manufacture to b the flanges 8 and J upon the score ll12; and this done, to next bend over fhips 10 and ll, so as to causethem to overlap the adjacent POTLTO:.1S.OID the flanges 8 and 9.

A'guide sheet 2. made of card-board. or other appropriate sheetmaterial, is next 1 l in position, so that i n To LS ends overlap thecent or inner portions of the end flaps l0 and 11, the sides of theguide sheet overlapping the exposed portions of the tonges or slides 25and 26. Thus the two edges of guide sheet 27 slightly overlap and endirectly the adjacent portions of the 8 and 9.

The guide sheet 27 is provided wit cirlar holes 28, so located that withthe sheet in position these openings are in registry with the tongues ofthe slides 22, if this instance four in number, as indicated in theupper left-hand corner of Figure 6.

Up to this in the manufacture there s no occasion for the use of radhesive any special mechanism, aside irom the respective terms given tothe vari parts, and the connection or" the various parts, as thus fittedtogether.

The next step of manuitact the other parts, as partially relation instdescribed, face sheet is other approp vided with circular holes 30positioned to re v above described with retere so to the holes 4.

sheet 1 and thus to register with the tongues of the adjacent slides.

The face sheet 29 has a pair of oppositely disposed edge portions 31 and32, integral with it. These edge portions 31 and 32, shown moreparticularl' in Figure 7, are glued or pasted firmly down upon theunderlying portions or the flanges 8 and 9, and are thus firmly secu edin position. 7

The only pasting or gluin required in my device or in the manufacturethereof, is between these edge portions 31 and 32 and the ent underlyingportions of the flanges No casting or gluing is necessary for one "uidesheet 2?, it being held in posiw itting into and among the other parts.l ce sheet 29 is provided with graphic shown, such as the words Butter,Tea, Tomatoes, etc, represent various items concerning which the ually ahousewife, seeks to be These legends are so located as in immediateassociation with the varil the slides are so arranged and other partsthat, by drawing ber oi? the slides, appropriate indications can bemade.

Tt will be noted from Figures 2 and 6 that some of tslides are providedwith longer tongues th 1 others, the slides with the long tongues bPlOTlClQLl with legencs 1 and 2. These par icular slides are used asindicated in the upper left-hand corn r of Figure 6 By pulling either ofthe slides outwardly the appropriate legend 1 or 2 is exposed to viewthrough the holes 28 and 30. The face sheet has lLS upper left-handcorner, accord ire 6, a number of legends wuer 1, Yeast- 2; Bacon 1, Ham1 Lentils 2; Bread 1, Crullers 2. oned legends are so arranged van. msrepresented by the legends can be indicated by the positions into whichthe slides are drawn out.

The various upper slides shown each has only two normal positions ;,onebeing when the slide is pushed inwardly to the limit of its travel, soas to register no indication, the other being when the slide is drawnoutwardly to the limit or its travel, in which event it makes onl singleindication, this indication being associated with a single one of thevarious legends above mentioned.

lily device being new practically completed, the last step is to 1 eke ahole 33 through it at its top, to facilitate hanging it upon a nail or ahook. T 1 ole can be made by a punch applied to the finished article; ormay, if desired, be produced by perforating the various cardboardmembers before they are assembled.

The operation of my device may be understood from the foregoingdescription. The device as a whole serves the purpose of a mechanicalmemorandum, and with the slides once arranged to make appropriateindications of the items concerning which the operator desires to bereminded, it will stay in that position for any length of time. I

The operator, in using the mechanical memorandum, first pushes all ofthe slides inwardly, the net result being that for the moment thememorandum registers no indications. Next the various slides, or such ofthem as are required, are drawn out as above described, so as to makethe appropriate indication.

I do not limit myself to the particular steps of the method abovedescribed,or to the precise mechanism illustrated and described, thescope of my invention being commensurate with my claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is as follows:
